Once removed from the pressure core testing tool, this specimen shows that it is not a homogeneous sediment.  The mostly fine-grained sample (dark sediment in all three images) easily breaks apart at a thin layer of coarse-grained sediment (light sediment on the inner core surfaces of images (i) and (ii).

A coral reef in the Turks and Caicos Islands dominated by the weedy coral species, Porites astreoides. The relative dominance of this taxa has increased throughout the western Atlantic.

Multibeam bathymetry shown in the spectrum from red (shallower) to blue (deeper) for depths greater than 200 m across the head of Astoria Canyon. The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.  The modern Columbia River is far right.

Topography and bathymetry of southern Cascadia, which includes southern Oregon and northern California (seafloor depths between 200 and 3000 m are shown in the spectrum color scale from red (shallower) to purple (deeper). The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.

Evolution of the shoreline around the Elwha River mouth, Washington, before, during and after dam removal, 2011–2017. Two large dams were removed from the Elwha River between 2011 and 2014 in the largest dam removal worldwide thus far, releasing more than 20 million tons of sediment downstream.

Above ground mesocosm with biofilm growth reactors. Groundwater from the well head is directly transferred to the mesocosm via PTFE tubing into a high flow rate control valve (a) that diverts groundwater into a flow cell containing a water quality measurement meter (b) and a low flow control valve (c).

 Two UNC mini landers, surrounded by Sablefish (Anoplopoma fimbria) and pink sea urchins, incubate seawater in situ to enable calculations of methane oxidation rates.

ROV SuBastian’s manipulator jaw stabilizes GEOMAR’s glowing bubble box that is capturing high-resolution images of methane bubbles rising from the seafloor.

Red plumes burst out from the tops of these chemosynthetic tubeworms, capturing hydrogen sulfide and oxygen from the surrounding water to feed their bacterial endosymbionts. The tubeworm tubes provide a habitat for several benthic animals, including the pale pink branching octocorals seen here
